Telangana or Telingana is an unofficial region in the Indian state of Andhra Pradesh. It includes the northwestern interior districts of Khammam, Mahbubnagar, Nalgonda, Rangareddi, Warangal, Karimnagar, Nizamabad, Adilabad, Medak, and the state capital, Hyderabad. The region lies on the Deccan plateau to the west of the Eastern Ghats range. Telangana is mostly Hindu and Telugu-speaking, although it has a significant Muslim and Urdu-speaking minority.

Telangana was formerly part of Hyderabad State, and was added to Andhra Pradesh in 1956 on linguistic grounds following the States Reorganization Act . There is an active political movement in Telangana that is seeking to secede from Andhra Pradesh to form a separate state, arguing that the underdevelopment of Telangana results from Andhra Pradesh being too big a state to govern effectively. In addition, they argue that the state government focuses on the more prosperous region of Coastal Andhra to the east. The Telangana Rashtra Samithi, a political party which advocates for a separate Telangana state, became part of the ruling coalition of Andhra Pradesh after the 2004 state legislative elections.
